I am trying to create a validation expression for a table name in the format of:
Name_TableName_YYYYMMDD
right now I have something like this:
^[a-zA-Z0-9][^_]+[a-zA-Z0-9][^_]+\d{8}
Number at the end can read 8 digits.

You could try this (very basic) expression
[a-zA-Z]+_[a-zA-Z]+_[0-9]{4}(0[1-9]|1[0-2])(0[1-9]|[1-2][0-9]|3[0-1])

Capture digit followed by bracket into two groups, then replace matched value with group values and multiple character between them:
Regex.Replace(input, #"(\d)(\()", "$1*$2")
For input "4.7(5+(8+3)/1(1-2))" result will be "4.7*(5+(8+3)/1*(1-2))"

Usernames Yes/No
“6789” Yes
“33333333_TL” No
“34567890-Shhh” No
“123456-Hero” Yes
“1234567” Yes
“New12345678” No
“87456773kk” No
“1234567890” No

See Regex to check for 4 consecutive numbers.
First check if your string's length >= 8 and then use a regex to look for N consecutive digits and if it finds a fit - your validation fails. Something like - /[^\d]\d{8}[^\d]/
