Answer 1

Yes. You can changes price of all items of a quote.

Use

$QuoteObjectitem->setCustomPrice($YourPrice);
$QuoteObjectitem->setOriginalCustomPrice($YourPrice);

Answer 2

Looking at quote_item table, you have the price column in that table. If you have an object of $quoteItem, you could set the price directly:

$quoteItem->setPrice($priceHere)

Also here is another answer from @AmitBera, how to update a quote item:

Magento 2 : Updating quote item

$item = $quote->getItemById($item->getId());
if (!$item) {
  continue;
}
$item->setQty((double) $qty);
$item->setCustomPrice($price);
$item->setOriginalCustomPrice($price);
$item->getProduct()->setIsSuperMode(true);
$item->save();
