PLEASE HELP!!! asap will leave thumbs up good review

Please help me create excel formulas for the question below. using these formulas preferred: TRIM(TEXT); FIND(find_text,within_text,start_num); LEN(text); MID(text,start_num,num_chars); RIGHT(text, num_chars, LEFT(text, num_chars).

CVRA-1333K37-AGW
F747-14GG371-AKR
919A-14g6712-AXR52
WW21-247945A-BBW

1) CREATE IN EXCEL IN THE NEXT COLUMN A FORUMLA THAT ONLY EXTRACTS THE PREFIX (for ex WW21-247.......) only from the first column and not from other columns.

2) CREATE formula that extracts he mid part of the number ( for ex CVRA-1333K37-...) only from the first column and not from other columns. (column A) note base middle part number can be from 3 to 10 characters (letters/numbers)

3) CREATE IN EXCEL IN THE NEXT COLUMN A FORUMLA THAT ONLY EXTRACTS THE SUFFIX (for ex ...-13G412-AGW) only from the first column and not from other columns. Column A.
