What is Tor entry guard?
The entry node, often called the guard node, is the first node to which your Tor client connects. The entry node is able to see your IP address, however it is unable to see what you are connecting to.
What are Tor guard nodes?
Tor guard nodes: A Tor guard node is the point of entry into the Tor network. Tor middle nodes: A Tor middle node is a Tor node that sits in the middle of the Tor network between a Tor guard node and a Tor exit node. A message can interact with multiple Tor middle nodes before reaching a Tor exit node.
Would having more number of relays make Tor more secure with increased anonymity?
Just adding more relays (and more relay capacity) doesn't always help. For example, adding more relay capacity in a part of the network that the adversary is already observing can actually *decrease* anonymity, because it increases the fraction the adversary can watch.
