E's-y T's: Word square fill in

Question

^{This is a follow-up to E's-y Word-Square Fill-in, but you don't need to know anything about that puzzle to solve this one.}

For each word square below, the Es and Ts have been filled in for you. Your task is to complete the rest of the square using exactly twelve other distinct letters. That is, you must pick any twelve letters of the alphabet (other than E and T), and use each of those letters one or more times. Each square uses a different set of twelve letters, although there may be overlap between squares. (e.g. if square (1) uses BFGKLMOPRSUZ, square (2) might use ABDFKMORSUVX).

The solutions contain only relatively-common English words that should be known to an educated native English speaker. There are no abbreviations, archaic words, foreign words, or anything else unusual.

$$\begin{array}{rcrc} \raise{3em}1. &\begin{array}{|c|c|c|c|c|} \hline \quad&\quad&\quad&\quad&\quad\\ \hline &&E&&\\ \hline &E&&&\\ \hline &&&T&\\ \hline &&&&\\ \hline \end{array} \quad\quad\quad\quad\quad \raise{3em}2.\quad &\begin{array}{|c|c|c|c|c|} \hline T&&&&\\ \hline \quad&\quad&\quad&\quad&\quad\\ \hline &&&&E\\ \hline &&&&\\ \hline &&E&&\\ \hline \end{array}\\ \\ \raise{3em}3. &\begin{array}{|c|c|c|c|c|} \hline T&&&&\\ \hline \quad&\quad&\quad&\quad&\quad\\ \hline &&&&\\ \hline &&&&E\\ \hline &&&E&\\ \hline \end{array} \quad\quad\quad\quad\quad \raise{3em}4. &\begin{array}{|c|c|c|c|c|} \hline &&&&T\\ \hline \quad&\quad&\quad&\quad&\quad\\ \hline &&&&\\ \hline &&&&\\ \hline T&&&&E\\ \hline \end{array}\\ \end{array} $$

While I can't prevent anyone from writing a computer program to solve these, I would encourage people to try it without. Where's the fun in brute-forcing a solution?
(Feel free to use a computer to help you find word patterns for a single word, just not to solve the whole puzzle.)

Answer 1

Just one ...Finally all four! (although I feel there could be "better" solutions for (1) & (2))

1. (The 12 other letters are: ACDGHILNORSZ)

 · · · · ·      Z I N C S
 · · E · ·      I D E A L
 · E · · ·  ->  N E G R O
 · · · T ·      C A R T S
 · · · · ·      S L O S H

(...although there's probably a solution without "zincs", it's not exactly a common transitive verb, and "negro" is probably considered archaic.)

2. (The 12 other letters are: CDHLMNOPRSUY):

 T · · · ·      T H U M P
 · · · · ·      H O N O R
 · · · · E  ->  U N C L E
 · · · · ·      M O L D Y
 · · E · ·      P R E Y S

(...I'm guessing U.S spelling is acceptable, since GentlePurpleRain resides in Canada; here in the U.K., where I am, it would be "honour" and "mouldy". Edit: apparently this is mostly true in Canada too.)

3. (The 12 other letters are: ADGIKLNORSVW):

 T · · · ·      T O R S O
 · · · · ·      O W I N G
 · · · · ·  ->  R I V A L
 · · · · E      S N A K E
 · · · E ·      O G L E D

4. (The 12 other letters are: ABCGHLMNRSUY):

 · · · · T      B L A S T
 · · · · ·      L U N C H
 · · · · ·  ->  A N G R Y
 · · · · ·      S C R A M
 T · · · E      T H Y M E
