I have been married to my husband of 8years and he filed for divorce, and we have 4 children. Can i get full custody?

Short answer: "maybe."  You do not provide any facts relevant to how a custody decision might be made.  For a list of the factors, links to the statutes, and a lot of other relevant information, including video explanations, see the materials posted at http://www.willicklawgroup.com/child-custody-and-visitation/. As to alimony, again you do not provide much information from which any intelligent evaluation can be made.  For a lot of information about how alimony works, see the materials posted at http://www.willicklawgroup.com/spousal-supportalimony/. To go over your individual facts, circumstances, options, and what is likely to occur in your case and why, you will need a consultation with a family law specialist who knows enough to evaluate your specific facts and circumstances, and advise you.
