Preg_match_all time catch multiple PHP

The formats I'm looking to catch using preg_match_all():

The regex I have so far: 

/((\d{1,2}|\d{4})(.\d{1,2}))(am|pm)*/i

Any help much appreciated, I can't seem to catch 5 & 6 with current regex.

How about:

/^(\d{1,2})([.:]?\d{1,2})?(am|pm)?$/i

Explanation:

/                   : regex delimiter
  ^                 : begining of string
    (               : capture group 1
      \d{1,2}       : one or two digit
    )               : end group 1
    (               : capture group 2
      [.:]?         : optional . or :
      \d{1,2}       : one or two digit
    ),              : end group 2 otional
    (am|pm)?        : am or pm optional
  $                 : end of string
/i                  : regex delimiter with caseinsensitive flag

You can use this regex:

/\b(\d{1,2})([.:]?\d{1,2})?([ap]m)?\b/i

RegEx Demo

Breakup of the regex:

\b       # word boundary
\d{1,2}  # match 1 or 2 digits for hours
[.:]?    # match *optional* dot or colon i.e. minute separator
\d{1,2}  # match 1 or 2 digits for minutes
([ap]m)? # match *optional* am/pm
\b       # word boundary
