Troubleshooting at bitrix24

Needs to solve for the given price the n/w problems:

1. in the deal I have a field which is called, for example, "DEAL NO." How to configure the field "offer no.", which is in the offer object, to: day / month / "NO DEAL" (which will be retrieved from the DEAL object).

Day and month I found how to configure this field, but I do not know how to break, it by "DEAL NR"?

2. is it possible to add a very wide and high field in the OFFER object? This field will be individual for each offer.

3.1 Alternatively, is it possible to make it so that if one selects X from the slider, an extensive Y text will pop up on the offer?

4. when another person creates a deal based on the company, it prompts him with a mass of contacts, which he must remove from the deal. On the other hand, when I create a deal, fortunately, the whole list is not prompted and I do not have to delete it?

5. is it possible that chat to deal is automatically created in the b24 version I have? Chat to deal not chat! Chat how to automatically create I know.

We would be happy to establish a permanent cooperation, a few hours a month.
