recomendation letters (should i keep looking)

I've been working for the past few months to secure recommendation letters for rush, and so far I've had a pretty good turnout. However, a few of my letters are from active members will those also be accepted?

Here are the amount of recs Ive secured for each sorority on campus.

Rate
Alpha Delta Pi - 1
Alpha Kappa Alpha - 0
Alpha Omicron Pi - 0
Chi Omega - 1 (On a serious hunt for a second)
Delta Delta Delta - 4
Delta Gamma - 3
Delta Sigma Theta - 0
Kappa Alpha Theta - 1
Kappa Delta - 2
Kappa Kappa Gamma - 1
Phi Mu - 1 (Also Seriously looking for a second)
Pi Beta Phi -2
Sigma Gamma Rho - 0
Zeta Phi Beta - 1

Based on what I have secured so far (Other than Chi O and Phi Mu) do I really need to keep looking for recs? Theres a few sororities I don't have any for, would it be a waste of time to find recs for each of them?
