When you view a Hand, a Hand Evaluation will show as you hover over each hand. This feature can be turned off in Web Administration - Settings - Scoring.

HCP

High Card Points. A = 4, K = 3, Q = 2, J = 1. Used to evaluate hands for most bidding.

Length Points

One point for each card over four in every suit. Can be used to gauge opening bids, responses, and rebids.

Shortage Points

Length Points plus doubleton = 1, singleton = 2, void = 3. Older alternative to length points, can be used to gauge opening bids, responses, and rebids.

Support Points

Length Points plus doubleton = 1, singleton = 3, void = 5. Also known as dummy points, can be used when supporting partner's suit.But NOT in Bid suit. Bridgewebs doesn't know whether the contract is trumps or no trumps or even what suit, so the Length etc points can apply differently depending on the bid, especially the Shortage Points

Controls

A = 2, K = 1. Used in some slam-bidding conventions.

Quick Tricks

AK = 2, AQ = 1½, KQ = 1, A = 1, guarded K = ½.

Losers

The losing trick count. Count only the top three cards in each suit. With three or more cards in a suit, A, K and Q are winners, lower cards are losers (maximum of 3). Note that Q98 or worse counts as 2½ losers. With two cards in a suit, A and K are winners, lower cards are losers (but AQ tight counts as no losers). With one card in a suit, A is a winner, any lower card is a loser. Void counts as no losers. Can be used to assess how high to bid. See The Modern Losing Trick Count by Ron Klinger.
