Is the money in my wallet considered unlawful if I used it to buy insurance shares, then sold them at a loss, and then used the remaining amount to buy mixed shares? What should I do about that? And is it obligatory to get rid of all the money? If I have adopted the opinion of those who ruled mixed shares to be unlawful, is it permissible for me to sell them and how should I dispose of them?

The purchase of shares in an insurance company and selling them at a loss does not affect the permissibility of the capital, as what returns to you is a portion of your capital. However, profiting from them is forbidden. It is permissible to follow those who have permitted investment in mixed shares, provided that the unlawful portion of their profits is disposed of. This is not like absolutely forbidden shares, such as those of usurious institutions and commercial insurance companies, for which it is not permissible to sell their shares.
