How can I code these if's conditions:

1)
If the first letter of the statement is "A" or number "2"

2)
If the second word of the statement is "join" or "joins" or "joined"

3)
If there's a phrase (eg paid by cash) in the statement

4)
Whether the phrase appears at the start, in the middle, or at the end of the
statement

The position of the phrase:
Statement 1: {phrase}... ... [start]
Statement 2: ...{phrase}... [middle]
Statement 3: ... ...{phrase} [end]


Thank you!
