Intention is a mental state that represents a commitment to carrying out an action or actions in the future. Intention involves mental activities such as planning and forethought.
Valid Wuzu is good for every worship as far as it is still valid. Any Wuzu performed for the sake of Allah is good for any worship.
It is highly recommended to recite Azan and more importantly Iqama for daily obligatory Prayers, but it is not obligatory. You can start you Prayer with out Azan and Iqama but you will be losing great deal of reward. Hadeeth states that if you recite Azan and Iqama and start your Salah, two rows of angles will pray behind you. If you recite Iqama then start your Salah, one row of angles will pray behind you. If you don't recite neither Azan nor Iqama and pray, you will pray alone then. Your prayer will still be valid but you will be losing great deal of reward.
Thank you for your question. Adhan and Iqamah are recommended acts so there is no problem in not performing them.
May you always be successful
Just to know in your heart that you are performing Qadha of the specific missed Prayer, for the sake of Allah (SWT).
'It is Makrouh (Disliked) to say your intention in your tongue. Intention is only in the heart in all worships. Only in Hajj and Umra rituals, it will be recommended to pronounce your intention.
To worship means to appoint someone/something as divine. This could be in practice, and it could be in one's intention and in their heart.
When any Muslim says or does something, then under no circumstance would they want to defy their religion and leave the perimeters of faith by ascribing a partner to Almighty God, or do shirk, or claim someone/something as being divine.
Any Muslim would know that there is only 1 God, and He has no partner, and He is the only Divine being.
Merely to say Ya, or Labayk does not mean the individual you are referring to is divine. A genuine seeker of the truth would certainly agree with this.
You can say Ya to God, and you can also say Ya to your neighbour, if you are drowning and seek help, for example. The Quran talks about this, saying Ya Musa (a.s.), and beseeching him, doing what we call istighatha.
To say Ya to someone alive, for the purpose of asking for help, cannot be irrational or haram.
Now, to say Ya to someone who is dead, is that ok?
Of course, we do not beseech help or assistance, or intercession from any person, but rather from those who are closer to Almighty God. Those who are considered as "waseelah" to Him.
And such people do hear us, even though they have departed this world, as the Quran [2:154] says:
Do not consider those who are slain for the cause of God to be dead. They are alive but you are unaware of them.
So, when we say Ya Muhammad, or Ya Ali, etc, it is not taken as worship at all. It does not fall under the category of 'ibadah, so how can it be shirk?
With prayers for your success.
Muslim female should not display her photos or videos etc in public even if her intention is not to attract, but she can never control the intentions of others.
Tawheed means not believing nor worshiping but only Allah (SWT). Shirk is believing or worshiping other than Allah with Allah (SWT). We believe that the Prophet and his Ahlul Bayt are the most humble servants of Allah.
Prostrating at the doorstep of the Prophet (SAWA) is in fact for thanking Allah for granting us the great bounty of visiting the shrine of the Prophet (SAWA) or his Ahlul Bayt (AS). Thanking Allah in the form of prostrating is a sincere worship to Allah and can never be Shirk. We never believe nor accept any claim suggesting worshiping the Prophet, his Ahlul Bayt or any one but only Allah (SWT). Respecting the Prophet and his Ahlul Bayt does not mean worshipping them at all. Respect is completely different from worshiping. Wahhabis mix wrongly between respect and worship. Even we prostrate at the doorstep of the holy shrines, we never do it as a sign of respect but we do it as an act of thanking Allah for His great bounties on us.
Thank you for your question. Shirk is to limit Allah in any way such that even the conception of another god would be possible. Even to say He is a god is not satisfactory as that would entail a genus of gods under which God would be a species with only one referent. Numerical oneness is limited, as in numbering God as one a person gives the possibility of two gods. Numbers themselves are a factor of the material world. Rather, Allah is above being numbered as a number entails a limit and He is above all limitations.
As for prostration, it is clear that if a person prostrates to a being in worship then that is completely forbidden in Islam and Shiism as a sect within Islam. However, prostration does not only entail this meaning and is also a symbol of humbleness. For this reason God commanded the angels to prostrate to Adam (as), not in worship or out of polytheistic intent. So too Prophet Ya'qub (as) prostrated in front of Prophet Yusuf (as).

Insofar as you are not intentionally worshipping or praying to the picture or the people and just had it there by accident, it is not shirk. However it is better not to pray in front of the picture (and you fixed that anyway so that is not a problem). Accidents happen!
If the person had the intention not to follow the Istekhara if it come out bad, the Istekhara is invalid. Istekhara means seeking guidance from Allah whether we like it or not. The intention of not following it if it come out bad means that the person is not seeking guidance from Allah through Istekhara, rather wants to dictate what he wants on the Istekhara. Such act is wrong and has no value.
It is not obligatory to perform Sajda al-Sahw for unintentionally saying Bismillah in stead of Tasbeehaat Al-Arba'.
It is permissible to place something solid in one's mouth while fasting, for the purpose of cooling down, or naturally creating saliva, as long as it is not swallowed, or taken out and placed back in mouth again.
An example for this is putting a coin in your mouth.
And Allah knows best.
