Selling scented candles and other scented products

Q: 

1. I wanted to open a candle making business where I make scented candles and candles using resin and epoxy with pearls and stones for decoration. Is this permissible? 

2. I also wanted to ask that my business will have everything to do with scents so sprays for the house and bamboo stick scents, candle massage oils and I’ll be selling to other companies like Checkers, YuppieChef and event planners to put as centre pieces for weddings. I would also like to do oud bars at weddings for customised weddings. I will also be selling ironing scents. Where, after the clothing is ironed it will be hanged and underneath it the bakhoor spoke will freshen the clothing. All of this will be from my home. 

Please remember me in your special duas, May Allah grant me barakah and Aafiyah.

Using the upper floors of a masjid for computer and school tuition classes

Q: There is a masjid which is 3 stories i.e. ground floor+2 floors. However, except for Jumuah Salah only the ground floor remains occupied and the rest of the floors are vacant. 

A group of community leaders have decided and infact what they have done is after taking permission from the Trustees have started a coaching class type thing wherein students from poor backgrounds are given computer and English and Science schooling in the first and second floors of the masjid at very nominal prices or for free. Basically a Muslim charitable trust is now using the upper floors of the masjid for teaching underprivileged kids computer and school tuition classes. 

Additionally they are now planning to use one area in the masjid in above floors as a Homeopathy clinic for free treatment for ailments. The entrance is separate from behind the staircase, not the main gate of the masjid.

My question is, is it allowed to use the masjid for dunyavi purposes in a manner the above people are using it? They are not using the main ground floor of the masjid but the first and second floors which are empty except for Jumuah. Please guide us with this question.
