<?php } else { ?>
<li class="ralign">
<?php } ?>
<div class="image">
<img src="<?php echo $spacategory['thumb']; ?>" title="<?php echo $spacategory['name']; ?>" alt="<?php echo $spacategory['name']; ?>" />
</div>
<div class="text">
<h3><?php echo $spacategory['name']; ?></h3>
<p><?php echo substr($spacategory['description'],0,150); ?></p>
<?php echo $text_view_more; ?>
</div>
</li>
<?php } } ?>

Answer 1

Change all instances of
$spacategory
to
$Spacategories[$i]
This will fix it.
Also, I don't see what's populating $text_view_more. You should probably change that to some data point from $Spacategories?
Finally, it seems you need to be looping based on the number of categories, so change
for($i=0;$i<8;$i++){
to
for($i=0;$i<$size;$i++){

Answer 2

In your code, $spacategory is not an item from $spacategories with the index $i in each iteration. You should have started the for:
$spacategory = $spacategories[$i];
or use a foreach instead:
<?php
$classesIndexMap = array(
0 => 'valign',
1 => 'lalign',
2 => 'talign',
5 => 'valign',
6 => 'talign',
7 => 'lalign',
);
$html_view_more = htmlspecialchars($text_view_more, ENT_NOQUOTES, 'UTF-8');
?>
<?php foreach($spacategories as $i => $spacategory) : ?>
<li class="<?= isset($spacategory[$i]) ? $spacategory[$i] : 'ralign' ?>">
<div class="image">
<img src="<?= htmlspecialchars($spacategory['thumb'], ENT_QUOTES, 'UTF-8') ?>"
title="<?= htmlspecialchars($spacategory['name'], ENT_QUOTES, 'UTF-8') ?>"
alt="<?= htmlspecialchars($spacategory['name'], ENT_QUOTES, 'UTF-8') ?>" />
</div>
<div class="text">
<h3><?= htmlspecialchars($spacategory['name'], ENT_NOQUOTES, 'UTF-8') ?></h3>
<p><?= substr($spacategory['description'],0,150); ?></p>
<a href="<?= htmlspecialchars($spacategory['href'], ENT_QUOTES, 'UTF-8'); ?>"
class="learmmore"><?= $html_view_more ?></a>
</div>
</li>
<?php endforeach; ?>
